The document discusses ways to protect the ozone layer from depletion. It first provides background on how the ozone layer is being depleted by man-made chemicals like CFCs and halons. It then lists five ways to protect the ozone layer: 1) Limit private vehicle use to reduce emissions; 2) Use eco-friendly cleaning products instead of toxic chemicals; 3) Avoid using pesticides which also contain chemicals; 4) Develop stringent regulations for rocket launches which release ozone-depleting compounds; 5) Ban the dangerous nitrous oxide which was not included in the Montreal Protocol. The document emphasizes individual actions like choosing cleaner transportation but also calls for government bans and regulations of industrial chemicals.
